Pressure control valve arrangement having pressure medium guiding surface integrally formed onto a projection of the cover

摘要

A pressure control valve arrangement for controlling a fluid pressure in an ABS brake system of a vehicle so that, while there is a tendency of individual wheels of the vehicle to lock, the brake pressure in at least one associated brake cylinder can be adaptively adjusted, including: a housing; and at least one diaphragm valve is accommodated in the housing, the diaphragm valve having a diaphragm as the valve body, which diaphragm can be acted upon by introducing pressure medium into a control chamber that is covered on the outside of the housing by a cover so that the control chamber is formed between the diaphragm and the cover, wherein at least one pressure medium channel carrying pressure medium is formed in the housing in the region of the cover, wherein at least one cover has at least one projection projecting into the pressure medium channel in the housing, a pressure medium guiding surface for directing the flow of the pressure medium carried in the pressure medium channel being formed on the projection.

1. A pressure control valve arrangement for controlling a fluid pressure in an ABS brake system of a vehicle so that, while there is a tendency of individual wheels of the vehicle to lock, the brake pressure in at least one associated brake cylinder can be adaptively adjusted, comprising:
a housing; and at least one diaphragm valve is accommodated in the housing, the diaphragm valve having a diaphragm as a valve body, which diaphragm is acted upon by introducing a pressure medium into a control chamber that is covered on an outside of the housing by a cover so that the control chamber is formed between the diaphragm and the cover, wherein at least one pressure medium channel carrying the pressure medium is formed in the housing in a region of the cover, wherein integrated in the cover is at least one projection projecting into the pressure medium channel in the housing, a pressure medium guiding surface for directing a flow of the pressure medium carried in the pressure medium channel being formed on the projection; wherein the projection having the pressure medium guiding surface projects into the pressure medium channel at a location at which the directing of the flow of the pressure medium within the pressure medium channel from a section of the pressure medium channel which leads in one direction into a section of the pressure medium channel which leads in another direction.
